The last cohort aged 6 to 23 months is fully enrolled and topline results are expected in first quarter of 2024.

COVID-Influenza Combination and Stand-alone Influenza Program

We continue to make strategic investments to prepare our CIC vaccine for advanced development.

We have selected the CIC dose formulation and we remain on track to initiate the next study in the second half of 2024.

Pending regulatory concurrence, we have designed this study to evaluate immunogenicity endpoints for accelerated approval while simultaneously expanding our safety database.

We have updated the study’s designation to a Phase 3 study.

While our focus remains on the combination product, our development plans will maintain optionality to advance our stand-alone influenza vaccine, creating a pathway to potentially seek licensure.

For our stand-alone influenza vaccine we have generated positive data through our previous Phase 2 trial and continue to believe this asset may be attractive from a pandemic preparedness perspective.

The neutralization responses were more than double seen with Fluzone® HD for the A strains and similar performance may be expected for A/H5N1 pandemic strains.

In May 2023, we announced preliminary topline data from our Phase 2 trial for CIC, stand-alone influenza and high-dose COVID-19 vaccine candidates.

All three vaccine candidates contain our Matrix-M™ adjuvant, showed preliminary robust immune responses, reassuring safety profiles, and reactogenicity that was comparable to the licensed influenza vaccine comparator arms.

We intend to further explore our options to progress select candidates into late-stage development.

High-dose COVID-19 Vaccine Study

In October 2023, we initiated a Phase 2 trial to evaluate our high-dose COVID-19 vaccine for annual vaccination in older adults.

The trial will compare immunogenicity levels of 5 micrograms of our prototype vaccine (NVX-CoV2373) against 5 micrograms, 35 micrograms, and 50 micrograms of our updated vaccine (NVX-CoV2601) that are matched with different levels of adjuvant.

Data from this trial is intended to potentially support further development of a higher dose formulation for older adults, similar to that of influenza vaccines.

The WHO recommended that the R21/Matrix-M™ adjuvant malaria vaccine be administered in a 4-dose schedule from five months of age.

This recommendation is a required step on the pathway to the WHO’s prequalification (“PQ”) of the vaccine.

PQ designation is necessary for United Nations agencies and partners, for example UNICEF and Gavi, to procure the vaccine for eligible countries.

This is the first recommendation from WHO to support the use of a vaccine containing our Matrix-M™ adjuvant in children as young as five months of age and it is based on the results from the Phase 3 clinical trial.

In September 2023, results from the Phase 3 clinical trial conducted in four African countries with 4,800 children aged 36 months to five years were published in a preprint manuscript in The Lancet.

The preprint manuscript reported that R21/Matrix-M™ adjuvant malaria vaccine is well-tolerated and offers high-level efficacy against clinical malaria in African children at sites of both seasonal and perennial transmission.

In July 2023, R21/Matrix-M™ adjuvant malaria vaccine received authorization in Burkina Faso and in April 2023, received authorizations in Ghana and Nigeria.

Business Highlights

Second Quarter 2023 and Recent Highlights

Net cash used in operating activities was $497.5 million for the six months ended June 30, 2023, as compared to $259.4 million for the same period in 2022.

Net cash used in operating activities was $537.2 million for the nine months ended September 30, 2023, as compared to $298.1 million for the same period in 2022.

The increase in cash used in operating activities is primarily due to a decrease in upfront payments received under our APAs, partially offset by the timing of payments to vendors.

Net cash used in investing activities was $31.3 million for the six months ended June 30, 2023, as compared to $41.4 million for the same period in 2022.

The increase in cash used in financing activities in 2023 as compared with 2022, is primarily due to the $325 million repayment of our 3.75% Convertible notes during 2023, partially offset by an increase in net proceeds from the sales of our common stock under our June 2021 and August 2023 Sales Agreements and the Private Placement with SK.

Going Concern

The accompanying unaudited consolidated financial statements in Part I, Item 1, “Consolidated Financial Statements” of this Quarterly Report have been prepared assuming that we will continue as a going concern within one year after the date that the financial statements are issued.

At June 30, 2023, we had $517.9 million in cash and cash equivalents and restricted cash.

During the six months ended June 30, 2023, we incurred a net loss of $235.9 million and had net cash flows used in operating activities of $497.5 million.

While our current cash flow forecast for the one-year going concern look forward period estimates that we have sufficient capital available to fund operations, this forecast is subject to significant uncertainty, including as it relates to revenue for the next twelve months, funding from the U.S.

government, and a pending matter subject to arbitration proceedings.

Our revenue projections depend on our ability to successfully develop, manufacture, distribute, or market an updated monovalent formulation of a vaccine candidate for COVID-19 for the fall 2023 COVID vaccine season, which is inherently uncertain and subject to a number of risks, including regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance.

Further, failure to meet regulatory milestones, timely obtain supportive recommendations from governmental advisory committees, or achieve product volume or delivery timing obligations under the Company’s advance purchase agreements may require the Company to refund portions of upfront and other payments or result in reduced future payments.

In February 2023, in connection with the execution of Modification 17 to the USG Agreement, the U.S.

government indicated to us that the award may not be extended past its current period of performance, which may result in us not receiving all of the remaining $250.6 million in funding as of June 30, 2023 we had previously anticipated.

At September 30, 2023, we had $666.4 million in cash and cash equivalents and restricted cash.

During the nine months ended September 30, 2023, we incurred a net loss of $366.7 million and had net cash flows used in operating activities of $537.2 million.

In accordance with Accounting Standards Codification 205-40, Going Concern, we evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that these unaudited consolidated financial statements are issued.

Our revenue projections depend on our ability to successfully manufacture, distribute, or market our COVID-19 Vaccine for the 2023-2024

vaccination season, which is inherently uncertain and subject to a number of risks, including our ability to obtain regulatory authorization, the incidence of COVID-19 during the 2023-2024 vaccination season, our ability to timely deliver doses and commercial adoption and market acceptance of our updated vaccine.

On January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration regarding an alleged material breach by us of the Gavi APA.

The outcome of that arbitration is inherently uncertain, and it is possible we could be required to refund all or a portion of the remaining Advance payment Amount of $696.4 million as of June 30, 2023.

See Note 3 and Note 15 to our unaudited consolidated financial statements in Part I, Item 1, “Consolidated Financial Statements” of this Quarterly Report for additional information related to the arbitration with Gavi.

The outcome of that arbitration is inherently uncertain, and it is possible we could be required to refund all or a portion of the remaining Advance Payment Amount of $696.4 million as of September 30, 2023.

See Note 3 and Note 14 to our consolidated financial statements in this Quarterly Report for additional information related to the arbitration with Gavi.

Management believes that, given the significance of these uncertainties, substantial doubt exists regarding our ability to continue as a going concern through one year from the date that these financial statements are issued.

In accordance with Accounting Standards Codification 205-40, Going Concern , we evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that these unaudited consolidated financial statements are issued.

In May 2023, we announced our Restructuring Plan which includes a more focused investment in our NVX-CoV2373 program, reduction to our pipeline spending, the continued rationalization of our manufacturing network, a reduction to our global workforce, as well as the consolidation of facilities, and infrastructure.

The workforce reduction plan included an approximately 25% reduction in the Company’s global workforce, comprised of an approximately 20% reduction in full-time Novavax employees and the remainder comprised of contractors and consultants.

The workforce reduction plan included an approximately 25% reduction in the Company’s global workforce, comprised of an approximately 20% reduction in full-time Company employees and the remainder comprised of contractors and consultants.

We have decided to progress CIC toward late-stage development and, as such, we are assessing the impact on our workforce requirements and ability to meet our future needs.

We incurred one time restructuring expenses of $14.7 million during the three months ended June 30, 2023.

We incurred one time restructuring expenses of $14.6 million during the nine months ended September 30, 2023.

See Note 15 to our unaudited consolidated financial statements in Part I for more details on restructuring.

We expect the full annual impact of the cost savings to be realized in 2024 and approximately half of the annual impact to be realized in 2023 due to timing of implementing the measures, and the applicable laws, regulations, and other factors in the jurisdictions in which we operate.

Our ability to fund our operations is dependent upon revenue related to vaccine sales for our products and product candidates, if such product candidates receive marketing approval and are successfully commercialized, and in particular the 2023 Fall vaccination campaign, which is inherently uncertain and subject to a number of risks, including regulatory authorization, ability to timely deliver doses and commercial adoption and market acceptance;

Our ability to fund our operations is dependent upon revenue related to vaccine sales for our products and product candidates, if such product candidates receive marketing authorization and are successfully commercialized, and in particular our 2023-2024 vaccination season, which is inherently uncertain and subject to a number of risks, including the incidence of COVID-19 during the 2023-2024 vaccination season, regulatory authorization, ability to timely deliver doses and achieve commercial adoption and market acceptance of our updated vaccine;

the resolution of certain matters, including whether, when, and how the dispute with Gavi is resolved;

and management’s plans, which include completing cost reductions associated with our global restructuring and cost reduction plan.

Our plans may include raising additional capital through a combination of equity and debt financings, collaborations, strategic alliances, and marketing, distribution, or licensing arrangements.

Our plans may include raising additional capital through a combination of equity and debt financings, collaborations, strategic alliances, asset sales and marketing, distribution, or licensing arrangements.

New financings may not be available to us on commercially acceptable terms, or at all.

Also, any collaborations, strategic alliances, and marketing, distribution, or licensing arrangements may require us to give up some or all of our rights to a product or technology, which in some cases may be at less than the full potential value of such rights.

In addition, the regulatory and commercial success of NVX-CoV2373 and our other vaccine candidates, including an influenza vaccine candidate, CIC vaccine candidate, or a COVID-19 variant strain-containing monovalent formulation, remains uncertain.

Also, any collaborations, strategic alliances, asset sales and marketing, distribution, or licensing arrangements may require us to give up some or all of our rights to a product or technology, which in some cases may be at less than the full potential value of such rights.

In addition, the regulatory and commercial success of our COVID-19 Program and our other vaccine candidates, including an influenza vaccine candidate and a CIC vaccine candidate, remains uncertain.

Also, the impact of our more focused investment in our COVID-19 Program, reduction to our pipeline spending, continued rationalization of our manufacturing network, reduction to our global workforce, and consolidation of our facilities and infrastructure remain uncertain.

If we are unable to obtain additional capital, we will assess our capital resources and may be required to delay, reduce the scope of, or eliminate some or all of our operations, or further downsize our organization, any of which may have a material adverse effect on our business, financial condition, results of operations, and ability to operate as a going concern.
